[PATCH 1/1] kern_tc.c: th_generation starts with 1 after overflow for single-core

Hello Gabriel,

the uniprocessor version uses an optimization at the reader side:

#if defined(RTEMS_SMP)
	} while (gen == 0 || gen != th->th_generation);
	} while (gen != th->th_generation);

This is possible since the windup happens with interrupts disabled. I 
guess you need this optimization somewhere in the PPS/NTP code.

Could you please add the details to the commit message and not the cover 
letter. The cover letter is not committed.

Could you please have a look at:
